This example demonstrates creating a stacked area chart with 3D effects.<br><br>
The key features demonstrated in this example are:<br><br>
<ul><li> Add a stacked area layer using <a href="XYChart.addAreaLayer2.htm">XYChart.addAreaLayer2</a> with the <a href="Chart.Stack.htm">Stack</a> predefined constant.<br><br>
<li> Add multiple data sets to the area layer using <a href="Layer.addDataSet.htm">Layer.addDataSet</a>.<br><br>
<li> Add a legend to the chart using <a href="BaseChart.addLegend.htm">BaseChart.addLegend</a><br><br>
<li> Add a title to the y-axis using <a href="Axis.setTitle.htm">Axis.setTitle</a>, and draw the title upright (instead of rotated 90 degrees) using <a href="TextBox.setFontAngle.htm">TextBox.setFontAngle</a>. Note that the title can contain multiple lines using line break characters.</ul>
